PHPMailer + HTML2PDF: pdf invalid and pj - php

Question

Good morning all ,
I would like to attach a PDF created following a form with HTML2PDF then send it with PHMailer.
Everything works, the email goes well, I managed to create the PDF by saving it on my hard drive.
But when I try to attach it to my email, the pdf is fine in pj but I can't open it.
enter image description here
It is the same size of my locally created pdf.
I followed the tutorial and wiki of the two libraries, well I think ^^
Here is my PHPMailer code:
<?php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
require './vendor/phpmailer/phpmailer/src/Exception.php';
require './vendor/phpmailer/phpmailer/src/PHPMailer.php';
require './vendor/phpmailer/phpmailer/src/SMTP.php';
require './vendor/autoload.php';
// Instantiation and passing `true` enables exceptions
$mail = new PHPMailer(true);
$mail->CharSet = 'UTF-8';
try {
//Server settings
$mail->SMTPDebug = 0; // Enable verbose debug output
$mail->isSMTP(); // Send using SMTP
$mail->Host = '******'; // Set the SMTP server to send through
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = '*****'; // SMTP username
$mail->Password = '*****'; // SMTP password
//$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` encouraged
$mail->Port = ****; // TCP port to connect to, use 465 for `PHPMailer::ENCRYPTION_SMTPS` above
//Recipients
$mail->setFrom('****#****.com', '****');
$mail->addAddress($to); // Add a recipient
//$mail->addAddress('ellen#example.com'); // Name is optional
$mail->addReplyTo($shop_email, 'Votre magasin');
//$mail->addCC('cc#example.com');
$mail->addBCC($shop_email);
// Attachments
$mail->addStringAttachment($pdf_done, 'myPdf.pdf'); // Add attachments
//$mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
// Content
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = $subject;
$mail->Body = $message;
$mail->AltBody = strip_tags($message);
$mail->send();
echo '';
} catch (Exception $e) {
echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
?>
and here is the code for HTML2PDF:
ob_start();
// --> mon code HTML de creeation du PDF
$content = ob_get_clean();
require_once dirname(__FILE__).'/../vendor/autoload.php';
use Spipu\Html2Pdf\Html2Pdf;
use Spipu\Html2Pdf\Exception\Html2PdfException;
use Spipu\Html2Pdf\Exception\ExceptionFormatter;
try{
$pdf = new \Spipu\Html2Pdf\Html2Pdf('P', 'A4', 'fr');
$pdf->writeHTML($content);
$pdf_done = $pdf->output('myPdf.pdf', 'S');
}catch(\Spipu\Html2Pdf\Exception\Html2PdfException $e){
die($e);
}
?>
I tried adding ", 'base64', 'application / pdf'" in the addStringAttachment but it doesn't change anything.
Do you have any idea of my mistake?
Thank you all

Debug one thing at a time. First download the PDF manually and make sure it looks correct – if the PDF is bad to start with, emailing it isn't going to improve things. Next check that it is readable from PHP – for example serve it using readfile(). Then when you try to attach it, check the return value of your call to addAttachment() like this:
if (!$mail->addAttachment('/path/to/myPdf.pdf')) {
die('could not read PDF');
}
Also note the difference between addAttachment and addStringAttachment; you're adding a file that's been saved to disk, so you want the first one, not the second.
